Just to be clear, I NEVER use my A/C's highest setting. What I meant by toggling on and off, while maintaining air circulation, is that I press the A/C button. This is the button with the "snowflake" on it. In other words, I'm likely to leave the setting on "2" throughout my drive. Also, I'm likely to use the "recirculate" setting throughout as well. This is technically not using the air conditioner, unless you've pushed the respective button.

The concept is basically the same as any other method of conservation. By limiting your use of the air conditioner, you are actively conserving fuel.

I hope this helps you understand what I'm talking about. I'm certainly more confused now.
